These arms efreceive the channel or holder 4, which in fectively protect the hand holding the handle when the knife, scissor, or other similar instrument is being honed. The hone 2 is preferably formed of plastic composition reinforced by a steel core 13 to render it less liable to breakage.

The. sharpening operation is accomplished as follows: The handle is gripped with one turn receives and embraces the sharpening member 5. The latter may conveniently consist of a steel tile which may be used for roughing off the edge to be sharpened, this edge being then finished on the hone. The sharpening member may be held in position in the channel or holder 4 by means of a -5 and then on the other, and pressing the hand, while the knife, scissor, or other similar instrument is held with the other and placed with one side fiat against the guide 7, the edge of the instrument to be sharpened being in contact with the sharpening surface, as shown by the dotted lines 14 in Fig. 2. By pulling the blade back and forth,

I claim as my invention:

I. In combination with a handle having a transverse aperture adjacent one end, of a channeled holder within the aperture, said holder being provided with angular flaring end portions for retaining the same in posi tion, and a sharpening member adjustably held in said holder, means for clamping the holder against the sharpening member, said flaring end portions serving as guides for the instrument. to be sharpened.

2. In combination with a handle having a transverse aperture adjacent one end, holder formed of spring sheet metal, said holder having a channeled body portion passing through the aperture, angular {iaring end portions formed on the holder adjacent to the mouths of the aperture, a sharpening member adjustably held in said holder, and means for springing the body portion so as to clamp the sharpening member in adjusted position to present a fresh sharpening surface, the flaring end port-ions serving as guides for the instrument to be sharpened.

same downward against the sharpening surface, a sharp edge will be obtained. The edge may then be finished olf on the hone to make it smooth and keen, a very few strokes being suflicient.

In the modification shown in Fig. 7 the set screw 6 operates in a bushing 15 sunk in the outer end of the handle. Otherwise the construction is the same as in the other form illustrated and described above.

From the above description it will be readily apparent that I have provided a sharpener which is simple. and inexpensive in construction and very eflicient in operation. The parts are very easily adjustable, as well as renewable. By securing the holder in the aperture by means of the guides, any outside means for securing the same is dispensed with. The facility with which the sharpening member may be released, moved to a new position presenting a new and unused sharpening surface, and there rigidly clamped by the set screw, enhances the utility of the device. The cost of manufacture is very low, as substantially all of the operations in forming the parts,
